  • Applications of butylidenephthalide
    Patent number: 11920157
    Abstract: Applications of butylidenephthalide (BP), comprising the use of BP in providing a kit for promoting differentiation of stem cells into brown adipose cells, and the use of BP in preparing a medicament, wherein the medicament is used for inhibiting the accumulation of white adipose cells, promoting the conversion of white adipose cells into brown adipose cells, inhibiting weight gain and/or reducing the content of triglycerides, glucose, and total cholesterol in blood.

  • Asymmetric bidirectional optical wireless communication system based on orbital angular momentum
    Patent number: 11736205
    Abstract: An asymmetric bidirectional optical wireless communication system based on orbital angular momentum comprises a system end device and a client end device. The system can split light into P-polarization beam and S-polarization beam, and utilize the orbital angular momentum multiplexing technology to increase the system capacity for uplink transmission in the client end device. In addition, the system also uses the combination of a beam homogenizer and a spatial light modulator to design an orbital angular momentum multiplexer with low energy loss, which can increase the number of orbital angular momentum channels by increasing the effective area of the components.
